We didn’t either, but Williams shared the story of her meet-cute with Rowling during a recent appearance on The Late Show With Stephen Colbert,

“Maybe my second year on The Daily Show, [Rowling] started following me on Twitter,” she told Colbert. “And I got really freaked out, and I thought, maybe she’s like, fake following me, like when Barack Obama followed like a million people and you’re like, OK, whatever. But she had like, actually followed me…and so then, I stopped tweeting, I got Twitter shy, because it’s like, what do you say at the altar? You know what I mean?…she ended up DM-ing me.”

The contents of the DM will make your heart melt. Apparently Rowling and Williams (along with Harry Potter) share a birthday and the author wanted to wish Williams a happy belated and tell her she was a huge fan of her work on The Daily Show.

The two women began corresponding via social media and a friendship was born. But Williams admits she still remained pretty starstruck. Although she was dying to know which house she belonged in, Williams didn’t think it was appropriate to ask via DM.

But don’t worry, she got her answer! The pair ended up hanging out in person (Rowling is “really, really cool” and easy to talk to, in case you needed another reason to love her) and Williams learned she’s a Gryffindor. Hearing it straight from the mouth of Rowling beats the heck out of all those online quizzes we’ve been taking.
